[Abstract]:In order to solve the problems of the magnetic path geometry model of air gap magnetic field using finite element method, a method based on the equivalent magnetization method is proposed to solve the magnetic field analysis of the air gap of the electromagnetic angular vibration table. The differential equations of vector magnetic potential are established based on the equivalent magnetization method, and the analytical expression of magnetic induction intensity including the geometric parameters of the magnetic circuit is obtained, and the validity of the equivalent magnetization method is verified by comparing the calculated results with the finite element method. The equivalent magnetization method is used to optimize the magnetic circuit parameters. The results show that when the thickness of the air gap remains constant, the effective and uniform magnetic induction intensity in the air gap becomes wider with the increase of the fan angle of the permanent magnet, but with the increase of the thickness of the permanent magnet, the intensity of the air gap magnetic induction will increase. When the fan angle and thickness of the permanent magnet remain constant, the magnetic induction intensity decreases with the increase of the air gap thickness. This method can rapidly analyze the influence of the change of magnetic circuit structure parameters on the magnetic induction intensity of air gap and provide a theoretical reference for the optimization design of magnetic circuit structure of electromagnetic angular vibration table.
